Use the Migration wizard to migrate from WebSphere Application
Server Version 4.x to Version 6.0.x.
Before you begin
Collect the following information about your Version 4.x installation
before you begin this procedure. The Migration wizard prompts you for the
information during the migration.
Legend: Supported versions
and their keys in the following table are:
- IBM WebSphere Application Server Advanced Single Server Edition Version
4.0.2 and later (V4.0.y AEs)
- IBM WebSphere Application Server Advanced Edition Version 4.0.2 and later
(V4.0.y AE)
- IBM WebSphere Application Server Enterprise Edition Version 4.1 and later
(V4.1.y EE)

Configuration file name |
Optional; defaults to config/server-cfg.xml file. |

No, if EE is installed on top of AE. Optional if
EE is installed on top of AEs; defaults to config/server-cfg.xml file. |

The name of the XML configuration file to process.
See WASPreUpgrade command for
a description of the import parameter. |
Use port values assigned to previous installation? |
Optional; defaults to false. |

Optional; defaults to false. |

Specifying “true” causes any ports of matching
VirtualHosts to first be removed from the new configuration before adding
the new values.
Specifying “false” for this parameter will just add
new port values.
See WASPostUpgrade command for a description of the replacePorts parameter.

Before using the Migration wizard, you must have access to
the existing, previous version of WebSphere Application Server. You must also
have a valid Version 6.0.x profile to serve as the target of the migration.
You
should have installed Version 6.0.x already. Use the Profile creation
wizard to create a new application server instance if the target profile for
the migration does not yet exist. After verifying that a valid Version 6.0.x
target exists, you can start the procedure.
Note: When you create the Version
6.0.x profile, the NodeName you choose must match one of the NodeNames in
the Version 4.0.x environment.
The
Network Deployment product does not create a profile during installation because
there are three profile types. The Installation wizard prompts you to create
a profile, but that action is optional during installation. Create a standalone
application server profile if you have not yet created one.
About this task
This article describes using the Migration wizard to migrate a
Version 4.0.x application server to a Version 6.0.x standalone application
server.
The Migration wizard is new as of Version 6.0.x. The wizard
is the graphical interface to the Version 6.0.x migration tools, which are
the WASPreUpgrade command and
the WASPostUpgrade command.
The migration tools are command-line tools.
You must supply the following
Version 6.0.x information about the target profile during the migration:

After gathering all of the information that is required during
the migration, use the wizard to migrate a Version 4.0.x application server
to a Version 6.0.x standalone application server.
- Start the First steps console.
./profile_root/firststeps/firststeps.sh
profile_root\firststeps\firststeps.bat
- Click Migration wizard on the First steps console.
The First steps console starts the Migration wizard. The wizard displays
its Welcome panel.
Click Exit on
the First steps console.
- Read the Welcome panel of the Migration wizard to learn about the
migration, then click Next.
The wizard displays the Detected
versions of WebSphere Application Server panel.
- Select a previous version, then click Next to continue.
Select the check box to specify the location of a previous installation
that might not appear in the list. Version 4.0.y AEs requires you to
identify the location of the configuration file. You do not need to identify
the location of the configuration file for other Version 4.x editions.
The
default location to use for the previous installation varies depending on
the Version 4.0.x product that you have installed. The following list shows
default locations:
- IBM WebSphere Application Server Advanced Single Server Edition Version
4.0.2 and later (V4.0.y AEs) uses a default location for the config\server-cfg.xml file.
- IBM WebSphere Application Server Advanced Edition Version 4.0.2 and later
(V4.0.y AE) uses the output from the XMLConfig tool.
You must have the Advanced Edition admininstrative server running during the
migration.
- IBM WebSphere Application Server Enterprise Edition Version 4.1 and later
(V4.1.y EE) uses the location of the product that it is extending,
which can be either AEs or AE.
If the previous version specification is correct, the wizard displays
the Migration backup directory panel.
- Specify a backup directory, then click Next to continue.
If the Version 6.0.x profile is valid, the wizard displays the Target
profile selection panel.
- Select the target profile from the list of valid profiles for the
installation, then click Next.
Use the Profile creation
wizard to create a target profile for the migration if one does not yet exist.
The
wizard displays the Port value assignment panel.
- Choose whether to use port values assigned to the previous installation,
or generate new Version 6.0.x port values that are already assigned to the
target profile, then click Next.
The wizard begins the
premigration. The wizard displays a Migration status panel during the premigration.
If
the premigration is not successful, the wizard displays a failure panel. If
the premigration is partially successful, the wizard displays a warning panel.
Correct
any problems and retry the migration.
If the premigration is successful,
the wizard displays an indication of success.
- Click Next to start the postmigration.
If
the postmigration is not successful, the wizard displays a failure panel.
If the postmigration is partially successful, the wizard displays a warning

Correct any problems and retry the migration.
If the postmigration
is successful, the wizard displays an indication of success.
